t tion, the ratchet-wheel and pawl of Fig. 13 A4 is a cover-plate having a removable engagement with the main frame, as shown, the said plate being held upon said frame in any suitable manner, as by screws a2.

A5 is a supporting-base for the main frame.

The keys B are preferably arranged in three transverse rows and are fulcrunied upon a stepped plate C, engaged with the frame A. The keys of the upger row are thus fulcrumed upon the upper step c, the next row of keys heilig fulcrumed upon the second step c, while the keys of the lower row are fulerumed upon the lower step c?.

C is a housing located above the stepped plate covering the keys thereabove, said housing being slotted on each side, as shown at cis and c4, for the passage of the keys, said slots serving also as guides for the keys as they are manipulated.

A6 is a crossbar of the main frame limiting the downward movement of the rear ends of the keys and holding the forward extremities of the keys in horizontal alinement. This cross-bar is preferably cushioned by a suitable covering d.

A7 is a slotted plate through which the forward ends of t-he levers B project, said slots serving as guides for said levers.

BJ denotes the spacer key or bar, provided with arms b', fulerumed upon the stepped plate C, one of said arms having a link connection with a corresponding lever 'E'. To restore the spacer-key to normal position, we provide springs b2, Fig. 1Q, engaged witheach of said arms, hooks B engaging the opposite ends of said springs, said hooks being supported upon a cross-bar d" of the main frame.

B4 represents keys for raising the typewheel, to be hereinafter described, `into position to use the upper-case letters, there being one of these upper-case keys on each side of the keyboard. At their inner ends these u pper-case keys are engaged with sleeves O7 (see Figs. t), 10, 1l, and 12) upon an oscillatory bar B5, provided with an arm B", upon which rests the shaft of the type-wheel. A spring b3, engaged with said arm, restores the arms with the upper-case keys to normal position. A hook b4, supported upon the crossbar ai, engages the lower end of said spring.

BT is a key for raising the typewheel into position for the use of numerals, punctuationmarks, or other characters. This characterkey B7 is connected at its forward end with an outer sleeve Zf upon the bar B5, said bar being also provided with collars li, rigidly engaged therewith, the sleeves and collars being so constructed that at a given point in the movement of the keys .3" and BT the respective sleeves will clutch the adjacent eollar and oscillate the bar E". The keys Bl are arranged to have a limited downward stroke to litt the upper ease on the type-wheel into proper position, while the clmracter-key B7 is arranged to have a f urther downward stroke for the purpose of lifting the type-wheel still higher to bring the numerals or other cha-raeters into proper position.

BS is a rotatable cam to lock the adjacent upper-ease key Bi in downward position to hold the upper ease of the type-wheel in operative position.

D represents a rotatable type-wheel, and D' is a shaft projecting downward through the cover-plate and resting on the end of the arm BG. D2 is a retraeti11g-spring upon said shaft. DI" is a pinion on said shaft, and 1) a segmental rack-bar on the shaft.

The type-wheel shai't is journaled in an upwardly-projectiilg bracket-arm AS on the cover-plate and made vertically adjustable.

E and E represent rocking frames mounted, respectively, upon rocking shafts Ez and lil, each of said frames being provided with side bars c e', oppositely inclined, said side bars being connected with the corresponding shaft by cross-bars c2. These frames E E' and their respective shafts are located end to end and separated at their adjacent ends, as shown, each frame operating independently of the other. Said frames are located above the levers B', said levers when raised by the depression of the corresponding keyengaging with said frames, the levers B' being preferably cut away, as shown at if, to adlnit the shafts of said frames when the levers are in raised position. The raising of the levers B', respectively, gives a rocking movement to the corresponding frames, the frames being restored to normal position by springs e3 when free to retract. The side bars c are constructed to give the individual levers B the amount of travel or throw required to move the type-wheel in position for the eorresponding character.

The angle of the fra-mes lil and lill, it will be obvious, must be very accurate on both sides thereof, so that when a given lever B is lifted it will Iirst come into contact with the front side bar c' ot the corresponding frame and bring up at the limit of its stroke on the rear side bar c, thereby bringing the tyjiewheel into the right position and holding the type-wheel in said position as long as the corresponding key is kept down.

lt will be evident that when the lever Vl strikes both the'i'ront and rear side bars of the corresponding frame it has reached the limit of its movement.

There is obviouslygreat advantage in making the two rocking Vframes separated at their adjacent ends over making a single `frame the same length as the two :frames put together, inasmuch as by making two such frames we are enabled to secure more readily the required throw to each of the levers B, this construction permitting of a greater difference of action between the various levers and thus giving more time for tripping the hammer and striking the right letter. Said shafts are provided with oscillatory arms E and E5, respectively, said arms having rackbars c and c at their upper ends meshing with the segmental, rack-bar D" upon the shaft oi' the type-wheel, whereby the type- IOO IIC

wheel is rotated into required position. The shafts E2 E5 are-journaled in suitable brackets A9, depending from the cover-plate. The

' arms E4 E5 project upward through the coverplate an'd are limited in their stroke by a stop-bar a5, having an adjustable engagement upon the cover-plate. The rack-bars eL e5 are held from any liability of lateral disengagement from the rack-bar l)4 by lugs d5 on the bracket AS.

F and F are spools upon which is wound the ribbon F2, which, intermediate the spools, passes about'the type-Wheel. These spools are mounted upon shafts F3 and F4, provided with ratchet-wheels fand f', the ratchet-teeth preferably standing upward at the periphery thereof, as shown. These shafts are also journaled in the bracket AS.

To shift the ribbons on the spools, we provide an/oscillatory dog F5, Figs. 2 and 3, arranged to alternately engage the two ratchetwheels, a spring f2 serving to hold the dog in engagement with one or another of said crank lever F8 on the under side of the coverplate, the opposite arm of said lever being united by a connecting-rod f8, Fig. 4, with an arm g of a rock-shaft G, j ournaled in brackets ai on the under side of the cover-plate. rlhe rock-shaft G is provided with a transverse wing or bar G', connected therewith by arms g', the bar Gl being located above the-levers B' and actuated thereby to rock the shaft G. Consequently on the operation of a given key the standard f5 is oscillated, whereby the dog F5 rotates one of the ratchet-wheels ff one notch, winding the ribbon on the corresponding spool. By throwing the pendulum over in one direction or the other the rotation of the spools is reversed. A spring f9 retracts the bell-crank F8 and consequently the dog F5.

H, Figs. l, 3, and 30, is a reciprocatory hammer to strike against the type-wheel to impress a given letter or character upon the intervening paper, said hammer being sleeved through an oscillatory yoke H', said yoke provided with journals H and H5, having their bearings in brackets (indicated by the numerals l and 2) supported upon the coverplate. These journals at their extremities are provided with heads Hl and H5, whereby the hammer may be turned up out of the way and returned to normal position from either side of the machine. Y

H5 is a spring to retract the hammer.

face 7i of the hammer may be made of steel or rubber or any other suitable material. A trip-hammer I, constructed in the form of a bell-crank, is provided to strike the reciprocatory hammer H, said trip-hammer having an oscillatory engagement upon the bracket, (indicated by the numeral 1,) said bracket being provided with an arm upon which the latter hammer is fulcrumed.

I' is a spring exerting its tension upon the trip-hammer. With the rear end ofthe triphammer is engaged an operating-rod I2.

EG indicates an oscillatory frame fulcrumed upon the shafts E2 E3, said frame being provided with side bars E7 and ES, engaged upon said shaft by end pieces e e7. This frame E5 is constructed with a rearwardly-projecting arm E9, with which is connected a rod I3. The oscillatory frame E5 is located about the rocking frames E E' and is actuated by the levers B. The frame E, however, is so located and arranged with reference to the rocking frames E E' as to be actuated by a given lever B' after the actuation of either of the rocking frames by a given lever, the movement first imparted to the one of the rocking frames by a given lever first actuating the type-wheel to bring it into required position, a further impulse or movement of the said lever actuating the oscillatory frame and thereby the triphammer to impress the corresponding type or character upon the paper.

The rod l2, Figs. 5 and 6, is engaged at its lower end with a crank-pawl I4 upon a spindle I5, sleeved in the bracket l, said spindle provided with a retracting-sprin g t. The rod 15 is connected with a bell-crank I6, fulcrumed upon said bracket, as at t'. The opposite end of the bell-crank carries an adjustable screw or plunger I7, arranged to strike against the end of said spindle and force it longitudinallyT forward when the bellcrank is operated, thereby forcingv the crank-pawl out of engagement with a stop t4, allowing the spring upon the trip-hammer to cause a blow of the trip-hammer upon the hammer H, the said crank-pawl I4, being released from said stop, engaging a rotatable toothed wheel 3,by,which it is returned to normal position, in the manner-hereinafter described,in engagement with said stop to hold the hammer in retracted position.

l8 is a thimble engaged in the bracket l to receive one end of the spindle and its retracting-spring.

19 is an arm on the end of the spindle provided with an adjusting-screw t2 to contact with an arm 'i3 upon the bell-crank 16.

It will be obvious that when the rod l5 is forced upward the arm t5 of the bell-crank 1G will be raised against the arm I on the end of the spindle l5, thereby giving a partial rotation to said spindle and throwing downward the outer end of the crank-pawl I4.

It will be seen that whenever a letter is struck and the carriage is moved a step there- The by the wheel 3 will strike the pawl I4 and IOO IIO

throw it down past the arm i" sufliciently to allow the spring i to pull the pawl I'l under the arm t, when the spring l will lift the pawl ll up snugly under the arm i* after it has been thus pulled therebeneath. In this lifted position the pawl I4 projects sufficiently to be ticked or struck slightly bythe wheel 3 in its step movement, but when the spindle I5 is partially rotated by the upward movement of the rod l5 the pawl Il is thrown down sufiiciently to allow the wheel 3 to pass without ticking. This is not essential to the working of the machine, but simply to prevent the noise that would follow if the wheel 3 were allowed to thus tick the pawl I4. The operation of the rod I3 trips the hammer to strike the letters and also throws the arm t3 upward sufficiently to turn the pawl I4 down a required distance to prevent its being ticked by the wheel 3, as above stated.

The arm 'i4 has a fixed engagement on the bracket 1 and holds the retracted erank-pawl thereunder until released by the movement of the spindle, as above described.

The trip-hammer is fulcrumed on a spindle 115 in the bracket l, upon which spindle is also located the spring I. The opposite end of the spindle is provided with a ratchet-wheel i6 and with a milled head fil'. A pawl 'is engages said ratchet-whcel, the pawl being provided with an operating-lever t.

'im is a segmental bar adjacent to said lever arranged to hold the lever in position at the upper or lower ends thereof. In this manner it will be seen the tension of the spring 1' may readily be changed by turning the head i? or by shifting the lever 279 to the upper or lower ends of the segmental bar 10.

Upon the shaft t is mounted a hub G, pro vided with a stem with which a toothed wheel 3 has a threaded engagement. A toot-hed wheel 5 is loosely mounted upon said hub. An additional toothed wheel 7 is mounted upon the shaft 4t and made fast to said hub (l, as by screws Q. Said wheel 7 is constructed with an arc-shaped slot 23, and the wheel 5 is provided with a spur or pin 2i, extending into said slot, a spring 25 exerting its tension upon said pin. By this arrangement the wheel 5 is only permitted to move one space orstep at a time, the wheel being moved back by said spring, one end ot' which is fastened to said pin and the other end thereof being secured to the wheel 7.

13 denotes a ratchet-wheel mounted upon the shaft et.

9 represents ahub or sleeve upon the shaft 4, with which is connected a spring S within an inclosing case 10.

The ratchet-wheel 13 and the case 10 are united, as by screws Q engaging the hubs of the ratchet-wheel and case. The wheel 7 is provided with a dog or pawl 1l to engage the ratchet-wheel 13 and preventing the retrac tion of the wheel 7 and the mechanism connected therewith. The hub 9 is provided with a shaft 15, connected with which is a milled head 16 and a ratchet-wheel17. Upon the shaft 15 is loosely mounted a crank-arm 1S, carrying a pawl 19, engaging the ratchetwheel 17, said wheel being made fast to the hub of the head 1G, said hub having a fixed engagement upon the shaft 15, as by a pin q.

Sleeved through the outer end of the crankarm is a reciprocatory spring-stop 20, engaging in a retaining-socket 21.

It will be apparent that by turning the shaft 15 either by means of the milled head 1G or by means of the crank-arm 18 the tension of the spring 8 may readily be increased or diminished, as may be desired, and that the spring may be independently adjusted either by means of the milled head 1U or the crankarm 1S. When it is desired to rapidly adjust the tension of the spring 8, the stop 2() may be released from the socket 21, the stop being provided with a head 22, permitting the operator to rotate the crank-arm 18 to rapidly adjust the tension of the spring. The stop is then engaged in the socket 21, when, if re quired, a closer adjustment of the spring may be made by means of the milled head 1G. The teeth upon the wheels 5 and 7 are spaced an equal distance from one another and are of equal size.

Upon the shaft G is located an oscillatory pawi G2, en gageable with the toothed wheels 5 and 7 upon alternate oscillations of said pawl. This pawl G2, it will be understood from the description heretofore given, is thus operated by means of the levers B engaging the bar G on the rock-shaft G. lVhen the lever l5' is lifted by the depression of the corresponding key, the pawl G2 is disengaged from the wheel 5, with which it is in normal engagement, and engaged with the wheel 7, said pawl engaging the spaces between the teeth oi' said wheel, said spaces being arranged opposite to one another.

It will be perceived that when the pawl G2 is released from the wheel 5 the spring 25 will throw the pin 21 to the limit of the slot 23, the pawl G2 at the same time engaging the wheel 7 and holding it from turning. The slot is of a length just sufficient to permit the wheel 5 being rot-ated by the spring 25 the distance of a single tooth, where the wheel 5 is held from further rotation while the pawl Gzisin engagement with the wheel 7. When the lever B' drops to normal position, the pawl G2 is disengaged from the wheel 7 and re'engaged with the wheel 5, the wheel 5 having meanwhile rotated, described, the distance of one tooth. The pawl G2, being disengaged from the wheel 7, permits the wheel 7 being rotated by the spring S to the limit of the slot 23, or the distance of one tooth, the rotation of the wheel 7 carrying with it a corresponding distance the shaft 4 with the wheel 3 and a toothed wheel 2G on its front end to operate other parts, as will be hereinafter explained. The operation of the wheel carries with it the crank-pawl I4, by means TOO IIO

of which the operating-rod I2 is thrown downward to bring the trip-hammer I into retracted position and bring a corresponding tension upon the spring I', said spring and hammer being thus retracted into normal position to be actuated to operate the hammer H. As the pawl I4 is forced downward thus by the rotation of the wheel 3 the spring e', retractin g the spindle 15, forces the pawl I4 under the arm t4, thereby locking the pawl I4 until the spindle I5 is driven forward by the operation of the bell-crank lever I5, as hereinbefore set forth.

D5, Fig. 7, is a pawl engageable with the pinion D3 on the type-wheel shaft DC This pawl is fulcrumed, as at d, intermediate its ends. With the opposite end of the pawl is engaged a connecting-rod D, leading rearwardly to and connected with an operatingbar D5, extended, essentially, at right angles thereto, said operating-bar being fulcrumed intermediate its ends, as at d. The opposite extremity of the bar D5 is led adjacent to the pawl 14, so that when the pawl I4 is moved by the spindle I5 out ofl engagement with the arm 4 the movement thereof will force in corresponding direction the outer extremity of the bar D5, thereby, through the connectingrod D5, operating the pawl D5 to throw said pawl into engagement with the pinion D5 to lock the type-wheel while being struck by the hammer H. The bar D7 is provided with a tilting dog cl2 to allow the pawl I4 to return to normal position. After the pawl I4 has been moved laterally out of engagement with the stop i4, thereby moving the bar D7, said bar returns to normal position before said pawl returns to its normal position. It becomes necessary therefore, inasmuch as the pawl I4 must be moved downward to rengage under the arm 4, that such a tilting dog should be provided to permit the downward movement of said pawl past said bar. The bar D7 may be returned to normal position in any suitable manner, as by a spring upon the fulcrum-pin d. (Shown in Fig.

J, Figs. 2, 3, and 17, denotes the paper-carriage, comprising a base J provided with a rack-bar J 2, meshing with the toothed wheel 26 upon the shaft et and by which the papercarriage is driven. 1

J3 and J4 are end pieces of the carriage, in which are journaled a feed-roller J anda spring-tension roller J 6.

K and K are bars engaged upon the coverplate A4, upon which the carriage is supported and upon which the carriage travels, the carriage being provided with rollers j, having their tread upon said bars K K. K2 are adjustable stops on one of said bars.

The bars K K are provided with elongated guide-recesses 7n 7c', Fig. 3, on their adjacent surfaces, into which project lugs j' and jz to hold the carriage in place. The carriage .is provided with rollers J7and JS in front of the feed-roller. .Y

J 9 is a sheet of cloth orother suitable fabric engaged upon the rollers J5 and J 5, said cloth arranged to wind upon the feed-roller when the. paper upon which the impression is to be made is inserted, the cloth unwinding at the same time from the roller J6, the spring J10 within the roller J 5 meanwhile being wound up, thereby increasing the tension of the spring, since the tension of said spring is utilized to wind the cloth back upon the tension-roller to feed the paper upward as the operation of the type-writer proceeds. The cloth passes over the rollers J7 and J 8. The cloth is led from the tension-roller under the feed-roller and under the roller J 8, thence over the roller J 7 and back under and thence about the feed-roller. It will be seen that by this arrangement the rollers J5 and JG may rotate in opposite directions.

The spring J10 winds upon a shaftj5, Fig. 17, within the roller J5. A ratchet-wheeljtL and milled head r7'5 are engaged upon aspindle 45, engaged with a hub 46, on which said shaft is sleeved,- for changing the tension of the spring, a pawl j engaging said ratchet-wheel, and the spring being engaged with said hub to permit increasing the tension of the spring while the roller J5 remains stationary. The feed-roller J5 is provided with a hand-knobjT, whereby the roller may be manipulated. The opposite end of the feed-roller is provided with two ratchet-wheelsj8 and j, the latter being rigidly mount-ed upon the adjacent journal of the roller, while the inner wheelj8 is loosely mounted thereupon.

J, Fig. 15, is a spring exerting its ,tension upon the ratchet-wheeljs, the spring being provided with a housing .112. The ratchetwheel js is provided with an elongated slot jm and the wheelj9 with a stud j, projecting into said slot, said stud made oscillatory and provided with an arm jig on its inner end and with an operating crank-army'13 on its outer end. The wheel jf) is provided with stops j and l7'15 to limit the movement of said arm. It will be evident that by moving the crankarm ,7'13 to the right or left the arm '752 will be thrown either to be brought into position longitudinally of the slot, as shown in dotted lines, Fig. 16, or at right angles thereto, as shown in full lines in said figure, in order to change the width of the spaces between the lines in the operation of writing.

The numeral 27 indicates a pawl, and 2S a laterally-oscillatory lever engaged toward one end upon a reciprocatory spindle 47, a nut on the end of the spindle limiting the movement of the spindle in one direction, the operatinglever 2S compressing the spring, permitting the pawl 27 to engage with the ratchet-wheel js, said pawl engageable with either of the ratchet-wheels js and jg as the lever 2S is shifted laterally in one direction or the other. Normally the pawl is in engagement with the outer ratchet-wheelj9 and serves to prevent the retraction of the feed-roller. Should it be desired, however, to feed the paper upward the distance of one line to another for the purpose of observing a word or line being IOO TIO

written, by throwing inward the lever 2t the pawl is engaged with the ratchet-wl ieeljs, permitting the ratchet-wheelj to retract a distance from one line to another, the retraction being occasioned by the tension roller J. Upon releasing the lever 2S the pawl is rcengaged with the ratchet-wheelj, permitting the ratchet-wheel j to be retracted by the spring J the distance from one line to another. If the eralilearlnjl is set so as to bring the arm j at right angles to the length of the slot jl", then the ratchet-wheelj9 and the feed-roller may be retracted, upon the engagement ot the pawl 27 with the ratchetwheel j, the distance of what is ordinarily called a double spaccg but should the arm jm be turned as indicated in dettedlines in Fig. il() then the feedroller would be retracted7 u nder these circumstances, a single space. It will he obvious that upon the engagement of the pawl 27 with the ratehet-wheeljS the wheel j would be retracted until the army"L strikes the limit ot the slot in the wheel jS in whichever direction the arm may be turned. "When the pawl 27 resumes its normal position in engagement with the wheel j, the wheel js rctraets until the arm j strikes the opposite end of said slot.

A spring 20 allows the lever 2S to yield inwardly and serves also to retract the said lever. In order that the paw 27 maybe operated from either side of the carriage in order to throw up the paper, as above described, the carriage is provided with an additional lever 30, Fig. l, on the opposite side, the levers 2S and 30 being united by a connecting-rod 3l and l'ulerumed in orifices at 52 in arms 53, as shown in Fig. 17. In case it should be desired to retract the feed-roller more than a single or a double space the pawl 27 is provided with an arm 3Q, by manipulating which the pawl may be thrown entirely ont of engagement with both the ratehet-wheels andj.

To limit the rotation of the feed-roll when the pawl 27 is out of engagement with bethel' the ratchet-wheelsfj", and thereby/limit the movement ot' the cloth in each direct-ion, the feed-roller is provided with a disk 33, provided with a tooth The adjacent end piece J4 of the carriage is provided with a stop -wheel 35, having a limited number of teeth, two teeth being shown in Fig. ll and three recesses adjacent thereto. The disk 233 and stop-wheel are in the nature of a Geneva stop.

lt will be evident from Fig. l-l that when the disk 33 has rotated so as to bring the tooth 3l into contact with the blank peripheral surface of the stop-wheel 35 the feedroller will be prevented from rotating an y farther in a similar direction. It will also be obvious that should the disk 33 be rotated in a direction opposite that indicated by the arrow the tooth 3l would engage successively with the various recesses of the stop-wheel until the stop-wheel has been turned into a position where the tooth would strike the blank periljiheral surface thereof, when the disk 33 would be locked again. ln thismanner all danger ot over-winding the spring in the tension-roller would be cffeetually prevented should the pawl 27 be entirely disengagcd from the ratchet-wheelsjij".

inasmuch as the disk is provided with three recesses to receive the tooth 3l, it is evident that the feed-roll may make four revolutions, the tooth illentering each ol' the three recesses, permitting three revolutions of the feed-roll, while said tooth may make one further revolution before it will strike the peripheral surface of the disk 35 and be stopped. It will be evident that with a feedroll off, say, three inches in circumference fou r revolutions will wind or unwind a sheet of paper of the length of twelve inches. lith a feed-roll of larger diameter a still longer sheet of paper may be wound and unwound thereon, or by providing the disk 35 with a larger number of recesses any desired length ot paper may be supplied tothe feedroll and fed therefrom.

Engaged with the knob ,jiis provided a device to turn up the paper to bring the line being written into sight, consisting ot a disk 3G, engaged upon the end of the shaft or jour nal of the feed-roller, the knob having a limited rotation thereabout independent there` ot' upon the disengagement ot' a stop or pin 37 with said knob. The pin is provided with. an operatiilglatch The surface of the knob adjacent to the disk 36 is provided with two lugs or stops E39 and l0 (sec Fig. 20) and with an orifice at l1 to receive the pin. The disk 3G has a stationary engagement upon the end of the journal, as by means of a screw 42.

It will be evident that by moving the latch 38 inward toward the disk the pin 37 will be removed from the orifice 4:1, permitting the knob to rotate until the pin strikes one ol' the stops. This will throw up the paper, so that the line being written will be in sight. The feed-roller may be rotated back to bring the line into its prior position without feeding the paper past said position by simply reversing the knob until the pin 37 strikes the opposite stop adjacent to the recess Ll-l, when the pinwill reenter said recess. A spring nt3 retracts the latch 3S into normal position.

lilarginal stops are provided at both ends of the machine in the following manner: L and L represent marginal stop-rods toothed at their outer extremities, as shown. ligand Lirepresent sleeves upon the reds L L', each provided with a bifureated arm l, extending rearward. adjacent to the rack-bar J2, as shown at Z', and downward, as shown at Z2. 'lhis bifurcated arm extends under the bar K. The sleeves are provid ed cach with a pawl Z3 to engage the toothed portion of the correspondingstop-rod. It will be obvious thus that the sleeves may cach be set upon its corresponding stoprod at any desired point to form a marginal stop at IOO ITO

, cated arm.

both ends of the machine,the rack-bar J2 being provided at its extremities with a stop f6 to strike against the arm Z to limit the movement of the carriage. The bifurcated arms Z are normally in position to be engaged by the stops jl as the carriage moves in one direction or the other. Crank-arms M M' normally hold the bifurcated armsZ in such position, said crank-arms normally bearing against the lower portion Z2 of the corresponding bi1" ur- It will be apparent that when the crank-arms M M' are removed from normal position the free ends of the bifurcated arm may drop away from normal position by gravity, the stop-rods L L' being journaled at their ends in brackets Z4 upon the rod K, allowing said rods to oscillate in said brackets when the weight of the corresponding arm Z is permitted to operate by retraction of the corresponding crank-arm.

The crank-arms M M', Figs. 2, 3, and 4, are engaged upon a transverse shaft M2, located on the under side of the cover-plate A4. Said shaft is provided at both ends of the machine with operating-levers M3 M4, by depressing either of which said crank-arms M M' will be retracted from said bifurcated arms. The shaft M2 is provided with a rearwardly-extended arm M, engaged upon one of the arms g' of the rock-shaft G, as by means of a link m, embracing said arm of the rock-shaft. It will be evident that when the shaft M2 is actuated by depressing either of the levers M3 M4 the arm M5 will tilt the rock-shaft G. The adjustment of the parts is such as thereby to throw the oscillatory pawl G2 entirely out of engagement with the toothed wheels 5 and 7, thereby allowing the carriage to be reciprocated freely in either direction. The crank-arms M M' may be locked in retracted position by means of a latch M6, Fig. 4, pivoted at the inner end of the lever M4, the inner end of the latch being constructed to wedge under the adjacent portion of the coverplate as the latch is moved inward, thereby throwing down the corresponding lever h 4 and holding it down while the latch is so engaged under the cover-plate.

It will be clear that the wheels 3, 5, and 7 can stand still when the carriage is being run back into initial position, as the carriage is only connected with said wheels through the pawl-and-ratchet devices 13 and 14, the pawl riding freely over the ratchet as the carriage is run back. lt will also be obvious that if the pawl be lifted from the ratchet-wheel the wheels 3, 5, and 7 will be free to move in either direction.

As already observed, the oscillatory pawl G2 is always engaged with the wheel 5 except when a key is depressed, and then it is moved into engagement with the wheel 7 and the wheel 5 is permitted to move one step. The pawl G2, however, may be moved out of engagement with both of said wheels 5 and 7 by means of the levers M2 M4 acting upon the crank-arm M5 and loop m lifting the bar G' into contact with the arm E9, and thereby forcing the rod l2 up to hold the crank-pawl I4 down out of the way of the wheel 3, said pawl being held thus out of engagement with said wheel until the operator releases the lever M3 or M4, when said pawl engages again under the arm 714 in the manner hereinbefore described.

Itwill be seen that a downward movement is given to the rod l2 by the actuation of the frame EG and its rear arm E, connected with said rod,while by the actuation of the shaft M2 by the levers M3 M4 an upward movement is given to the said rod l2 for the purpose hereinbefore described.

44 indicates a bar for guiding the paper as it is fed upward against the ribbon upon the periphery of the type-wheel.

N is a shaft supporting paper-guides N' N2, sleeved thereupon and made adjustable, setscrews n holding the guides in place upon the shaft. The shaft N is supported at its extremities upon standards N3 N4, bifurcated at their lower ends and sprung over the j ournals of the feed-roller, from which they are removable. The shaft NA is connected by a fork P with the yoke H', whereby the shaft N may be tilted over with said yoke. The shaft N is thus made to be tilted over with said yoke in order to insert and remove the paper.

The fork P has a movable engagement with said yoke, as well as a jointed engagement therewith, the yoke being constructed with elongated recesses ZL', permitting the adjacent end of the yoke to have a reciprocatory movement in said recesses. The fork is constructed with an arm P' normally resting upon the upper surface of the yoke.

The operation of the device will now be understood. The paper is fed into the guides N' N2 to the feed-roller, the rotation of which, with the rotation of the tension-roller and the consequent movement of the cloth con nected therewith, draws the paper into the machine land rolls it about the feed-roller. The paper is fed upward to the work in theI operation of the machine by the tension of the spring in the tension-roller J 4. The paper may be instantly thrown out of the machine by releasing the pawl 27, whichis done by pressing on the arm 32. Should more tension be required or desired upon the hammer for manifolding, it may readily be applied by moving the lever Z2 as above described.

Then a key is depressed by the operator, the corresponding lever B' is raised against the rocking frames E E' to actuate said frames, whereby the type-wheel is moved into required position. In the further upward movement of the levers B' at the end of the depression of the corresponding key the oscillating frame E6 is successively tilted, thereby actuating Vthe mechanism to release the trip-hammer I and permitting it to strike the hammer H. The mechanism holding the triphammer in normal position being thus re- ICO IOS

the lines, while the carriage may be retracted and governed by the marginal stops, as set forth. rlhe tension of the various springs is readily adjusted as may be re piired.

l-S denotes a metal easing partially surf rounding the type-wheel, having a ent-away portion adjacent to the hammer, through which the hammer maystrike the type-wheel, the casing serving as a protection to said wheel. lace of said case.

El represents the hell, which may be actu` ated by the movement of the carriage in anyl desired manner.

It will be seen that the bar 4t keeps the paper away fronrthe ribbon, while the device 4S keeps the ribbon from the type-wheel.

As shown more particularly in Figs. 13 and lt, the bar it is carried by a e 'ank-arm 50,

having a jointed engagement upon the adja-` cent end piece of the carriage, as shown at 5l, said crank-arm also carrying the journals of the roller J7, by which the bar -l-lis permitted to swing up as more paper is rolled into the machine.

The casing At8 is provided with a central spur adjacent to the normal position of the hammer Il to guide the operator in adjusting the carriage in required position to strike a given character.

le prefer to construct the rac.k,bars c* er with their inner teeth, as at es, longer than the other teeth, so as to more fully insure their taking hold upon the rack-bar upon the type-wheel shaft, the corresponding recess in said rack-bar being also cut deeper. This will secure a more positive action.

It will be observable from Fig. l that the fork F" is shifted autonn'ttically to the rightor left by the iilling up of the ribbon upon the spool on either side, whereby the pendulum will be carried past the center of gravity and thus swing over to change the feed of the ribbon.

The design. of the lever t is to increase the tension of the spring l for manifolding.

The pawl G2 is engaged upon the rock-shaf t G by means of a hub GS, provided with an arln g2, Figs. 2G and 27. Upon the said shatt is located an additional hub l", provided with an arm g3. G" aud G'I are adjusting-screws engaged with the arms g2 g3 to govern the movement of the pawl G2 to make the carriage feed fasteror slower, as may be required. By means of said adjusting-screws it will readily be seen the position of the pawl G2 radially upon the shalt may readily be regu- 'lhe ribbon passes over the exterior lated to govern the throw ol said pawl. rlhe hub G" is sleeved upon the shaft G and is lfree to turn thereupon, it being prevented from endwise movement by the hub G, keyed to the shaft., and by a collar at the opposite end ol the hub Gi", also keyed to the shaft, as shown.

lt will be observed that the stops jl are rounded on their lower corners, Figs. 21 and 29, and that the upper portion ci the arm Z is beveled on its upper edge.

1When the arm l has been removed out of the path of the carriage by depressing one of the levers M3 M", as hereinbelore described, permitting the writer to write on beyond the normal position of the stop as the carriage moves in one direction, this rounding of the lower corner of the stop and the bcveling of the upper edge of the arm l allows the carriage to ride back in the opposite direction, the stop, however, limiting the successive movement ot the carriage.

rlhe employment of two frames E E', as hereinbel'ore described, while permitting a greater throw to each lever ll at the point of contact of the levers with said frames, lessons the required throw of the (.orresponding key i3 at its outer end. Thus by uniting the levers l/ by links B2 with the corresponding keys ll and employing two rocking frames located end to end we are enabled to secure the advantages described, together with a lesseuing of the required throw of the corresponding key. The greater the movement of the rocking frames where the levers l j contact therewith the less nicetyol. construction is required in the remaining mechanism for operating the type-wheel.
